Sirena 64 Sea Trial

Italian styling and Turkish craftsmanship combine in a family cruiser.

“NEITHER SNOW NOR RAIN nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds” is the unofficial motto of the U.S. Postal Service. I think marine industry writers and boat reviewers should have a similar motto: “Neither size of seas nor strength of wind nor pelting of rains stays these sea trialers from their scheduled appointments.” We cannot always wait for perfect conditions and test boats on flat seas and in calm winds, like readers see in the photos that accompany a story. Due to builders’, brokers’ or our own schedule, we go when scheduled.

Which brings us to the sea trial of the Sirena 64. Two weeks of steady 20- to 30-knot east winds caused erosion along the Florida shoreline and fetched sizable capped rollers, and the conditions persisted as I tested the mettle of the new Sirena 64. Withholding a potential reputation for breaking new boats, I mentioned to Sirena Yachts Capt. Mike Giles that we may want to reconsider as we exited Port Everglades in Ft. Lauderdale, into the frothy sea.

Giles gave me a look that essentially said, “Are you kidding?” But he did say he recently undertook a sea trial in worse conditions, with an owner.

“We hit close to 10-footers” he said, assuredly. Basically, this day was a walk in the park for the Sirena 64.

Here’s a tip. Before you plunk down good coin for a boat, observe the hull. I was able to see the Sirena 64 on land a few days prior to our sea trial and had an idea how it would handle the 4- to 6-foot waves we experienced. A very sharp axe bow for entry is coupled to an aggressively long and wide chine that starts about halfway up the bow, creating a configuration that not only cleanly slices the waves but also reduces slamming and adds buoyancy. There’s no diving into the waves with green water crashing over the bow like in an old Navy movie. The bow stays up and the only water we received at the flybridge helm was from the wind-whipped spray.

Most folks may not head out on a day like this, but if getting home is required, the Sirena 64 is up to the job. And for those calmer, flatter days, it’s a great platform for family and friends.

Powered by optional twin CAT C12.9 1,000 hp engines — standard are twin CAT C12.9 850 hp — we made good headway despite the tough conditions. We cruised at 16.4 knots at 1800 rpm, at which point the twin CATs were burning 53 gph total. Pushing it, 2100 rpm yielded 22.6 knots, averaged on a reciprocal course, and an 80 gph fuel burn. Wide-open throttle, 2350 rpm, yielded 25.6 knots and a 100 gph burn. This is a touch lower than the spec sheet speed of 28 knots, but then again, in these conditions I was surprised to see what this yacht could do. On a calm day and with the ability to work the trim tabs, the Sirena 64 should easily attain 28 knots.

Calm conditions and trim tabs manipulation should enable the Sirena 64 to attain 28

Those CAT engines, by the way, are mounted in a V-drive configuration, which pushes them a little farther aft. The net result is more interior living space on the lower level, making the 64 feel larger.

In the engine room, diamond-plate floor coverings provide sure footing. Daily maintenance items such as dipsticks and Racor and CAT fuel filters/water separators are easily accessible. Each floor plate has a small metal plate affixed to it that specifies what is below, removing the guessing game. If chosen, the optional Seakeeper stabilizer gyro is mounted centerline, creating a raised box that is also covered and can be walked on/over. The CATs are surrounded by safety rails, which serve to keep exposed skin off the hot engines and offer a grab point. Beats touching a hot turbo.

Forward on the lower level are three staterooms (a fourth smaller room can be optioned and fits under the staircase). Amidships is the full-beam master. And its design is simple elegance. Large hullside windows — 22 inches high by 80 inches long — and 6 feet, 4 inches of headroom will cure any feelings of claustrophobia. The light and airy room is finished in light oak wood and fabrics. A portside full-length, contoured settee is great for private lounging. The master berth has storage below it, and a uniquely designed double-seat vanity runs along the starboard side.

Full beam is the master head, with Corian countertops, his-and-her Vitra basin sinks with Artema faucets, a separate toilet room (Tecma toilet) and an oversized shower stall with teak benches and flooring.

From the lower foyer, there’s access to the twin-bunk guest stateroom to port. A center nightstand, a hull window with an opening port, a hanging locker and 6 feet, 4 inches of headroom are essential. An en suite head includes a glass shower stall with a teak bench and flooring.

Forward is the VIP, which features a centerline double berth with storage below, a locker, a vanity with a seat and an overhead hatch with a ladder for egress. Corian counters, a separate shower stall and an opening port are in the en suite head.

A day head is accessible from the lower hall, fully appointed like the other heads. No skimping here.

Gathering locations abound on the main deck. Enter the aft deck via the swim platform or through 21-inch side boarding gates. Here, there’s a transom bench seat that has thick cushions and is fronted by two split teakwood tables that fold out to make a single dining table, easily converting from casual to formal in seconds. Sirena offers 7 feet of headroom on the aft deck.

Forward along the sidedecks — they offer 38-inch-high bulwarks and are great from a safety aspect — is the raised foredeck, which allows for ample headroom in the lower VIP. Fitted out with an oversized lounge/sunpad, the bow also includes an aft U-shaped settee with backrests and a teak table. Available is a high-low table that converts the settee to another sunpad. Nice touches include the popup light stands, a Bimini foredeck cover with carbon poles, recessed anchor tackle and storage for lines and fenders.

Triple glass doors between the aft deck and salon slide to starboard and convert the individual areas into one. Sirena Yachts North America sales rep Harold Del Rosario explained the concept for the layout, designed by Tommaso Spadolini of Design Studio Spadolini.

“Why divide two key social areas by putting the galley aft?” he said, adding that with the galley forward to port, the salon/aft deck work in collaboration for guest enjoyment.

Del Rosario also pointed out that the galley has a pass-through window and is open on the side, all of which can be enclosed by glass that becomes translucent at the touch of a button, as Sirena yachts are semicustom vessels.

Using dual L-shaped sofas, wood flooring and Nubuk materials, Sirena creates a casual yet classy environment. (Nubuk is the outer side of a hide, while suede is the inner side. Nubuk is more durable and more expensive.)

Up top, the flybridge is a statement in comfort.

Fitted with Miele appliances, the galley is fully functional thanks to the full refrigerator/freezer, a four-burner flat cooktop, a dishwasher and a microwave/convection oven. Twin Franke stainless sinks include an area for an angled dish drain. Good thinking.

Across the galley is a glass dining table with a bench seat and chairs. Forward is a pantographic door for starboard deck access.

The lower helm is to port and features a double-wide helm seat. An additional lounge seat next to the helm is perfect for guests. With a full array of electronics, including dual 10-inch Garmin GPSmap XSV displays, separate engine monitoring displays, thruster controls, left-side joystick and throttle controls, and every other required control, the helm is busy but functional. With a low-profile design at the helm and throughout the yacht, lines of sight are exceptional forward, sideways and even aft.

Up top, the flybridge is a statement in comfort. Passengers can dine at a large U-shaped settee with a teak table or relax on the sunpad next to the port-situated helm. The refrigerator/freezer console has a foldout countertop, which creates an L-shaped serving counter. An electric awning is built into the hybrid carbon-fiber hardtop. Buyers can add a crane and water toys on the flybridge aft deck.
